Create a feature to verify numbers with Twilio, without exceeding limit in all env except production.

[creaturenex]

Twilio does not offer a free testing sandbox as a result users pay for every message sent over the network. We need to either limit the message being sent or somehow mock a valid message response. This would apply in all env except production.
